  • Adding to %TIME% variable in windows cmd script

    - by Peck
    I realize that this could probably be done easier in any number of other scripting languages but started to do it quick in cmd and now Im curious. Looking to start a process at an offset to the time that another process started. Lets say 5 minutes to keep it simple. Is there a way to add to the %TIME% variable? For instance: start /b foo.exe at %TIME% + 5 minutes bar.exe Thanks for any assistance

  • classic asp - response.redirect and response.write problem

    - by apg1985
    Hi People, The problem if someone types into the search box a location it goes through to that location page but if they type in a location thats not found or they dont type anything in I need it to redirect back to the homepage (index.asp) and display "whoops we couldnt find that" in the search box (input field) This is the vb Case Else response.redirect "index.asp?whoops=whoops we couldnt find that" End Select Then in the value of the input field I have value="<% =whoops %>" This doesnt work by the way, first is this the best way of doing it because id rather not have the error message in the url. This there away of posting the error as a variable and then calling it into the input field like, <% =whoops %>

  • Variable naming for arrays - C#

    - by David Neale
    What should I call a variable instantiated with some type of array? Is it okay to simply use a pluralised form of the type being held? IList<Person> people = new List<Person>(); or should I append something like 'List' to the name? IList<Person> personList = new List<Person>();

  • Idiomatic ruby for temporary variables within a method

    - by Andrew Grimm
    Within a method, I am using i and j as temporary variables while calculating other variables. What is an idiomatic way of getting rid of i and j once they are no longer needed? Should I use blocks for this purpose? i = positions.first while nucleotide_at_position(i-1) == nucleotide_at_position(i) raise "Assumption violated" if i == 1 i -= 1 end first_nucleotide_position = i j = positions.last while nucleotide_at_position(j+1) == nucleotide_at_position(j) raise "Assumption violated" if j == sequence.length j += 1 end last_nucleotide_position = j Background: I'd like to get rid of i and j once they are no longer needed so that they aren't used by any other code in the method. Gives my code less opportunity to be wrong. I don't know the name of the concept - is it "encapsulation"? The closest concepts I can think of are (warning: links to TV Tropes - do not visit while working) Chekhov'sGun or YouHaveOutlivedYourUsefulness. Another alternative would be to put the code into their own methods, but that may detract from readability.

  • Objective C: Initalizing static variable with static method call

    - by adranale
    The Compiler claims an error saying: "initializer element is not constant", when I try to initialize a static variable inside a method with a call to a static method (with + in its definition). Anyway I can tell him that this method always returns the same value. I know this is not the same as static method, but there seems to be no constant methods in Objective-C (other than macros which won't work here because I am calling UI_USER_INTERFACE_IDIOM() from inside the method).

  • Collaboration Diagrams: how to represent setting a variable's and attribute's value to a specified v

    - by devoured elysium
    Let's assume I have a class called MyClass with an attribute called MyAttribute and a method called MyMethod(). Inside that method I'd like to have a variable called MyVariable. I'd like to set the value of MyVariable to "MyVariable" and MyAttribute to "MyAttribute" inside the call to MyMethod(). How can I do this in a Collaboration Diagram? I can't find any info of this kind on the internet and the book I'm studying from (Applying UML and Patterns) is very vague in the details. Thanks

  • How to get child container reference in View Model

    - by niels-verkaart
    Hello, I´m trying to share a Data Service (Entity Manager) wrapped in a Repository from a ViewModel (called 'AVM') in Module A to a ViewModel (called 'BVM') in Module B, and I can't get this working. We use PRISM/Unity 2.0 This is my scenario: A user may open multiple Customer screens (composite view as mini shell) each with another customer (unit of work). We realize this using child containers. Each child container resolves it's own repository with its own Entity manager (the repository is a singleton within the child container). This is done in module A. The main shell has a main region manager, and each Customer screen with its childcontainer creates a scoped region. In each customer screen there is a View 'AV' (connected to ViewModel 'AVM') with a SubRegion (tab control) registered as 'SubRegion'. We create this with a 'Screen Factory' In Module B we have a Customer Orders in View 'BV' and ViewModel 'BVM'. In the constructor of Module B we get the main container by injection. In the initialize method we resolve the (main) region manager and register View 'BV' with it. In the constructor of View 'BV' a ViewModel 'BVM' is injected/created. Now this works, but the ViewModel 'BVM' cannot get the child container. It only get the main container. Is this doable, or do I have to do this another way? Thanks, Niels

  • asp.net InsertCommand to return latest insert ID

    - by Stijn Van Loo
    Dear all, I'm unable to retrieve the latest inserted id from my SQL Server 2000 db using a typed dataset in asp.NET I have created a tableadapter and I ticked the "Refresh datatable" and "Generate Insert, Update and Delete statements". This auto-generates the Fill and GetData methods, and the Insert, Update, Select and Delete statements. I have tried every possible solution in this thread http://forums.asp.net/t/990365.aspx but I'm still unsuccesfull, it always returns 1(=number of affected rows). I do not want to create a seperate insert method as the auto-generated insertCommand perfectly suits my needs. As suggested in the thread above, I have tried to update the InsertCommand SQL syntax to add SELECT SCOPY_IDENTITY() or something similar, I have tried to add a parameter of type ReturnValue, but all I get is the number of affected rows. Does anyone has a different take on this? Thanks in advance! Stijn

  • Refactoring ADO.NET - SqlTransaction vs. TransactionScope

    - by marc_s
    I have "inherited" a little C# method that creates an ADO.NET SqlCommand object and loops over a list of items to be saved to the database (SQL Server 2005). Right now, the traditional SqlConnection/SqlCommand approach is used, and to make sure everything works, the two steps (delete old entries, then insert new ones) are wrapped into an ADO.NET SqlTransaction. using (SqlConnection _con = new SqlConnection(_connectionString)) { using (SqlTransaction _tran = _con.BeginTransaction()) { try { SqlCommand _deleteOld = new SqlCommand(......., _con); _deleteOld.Transaction = _tran; _deleteOld.Parameters.AddWithValue("@ID", 5); _con.Open(); _deleteOld.ExecuteNonQuery(); SqlCommand _insertCmd = new SqlCommand(......, _con); _insertCmd.Transaction = _tran; // add parameters to _insertCmd foreach (Item item in listOfItem) { _insertCmd.ExecuteNonQuery(); } _tran.Commit(); _con.Close(); } catch (Exception ex) { // log exception _tran.Rollback(); throw; } } } Now, I've been reading a lot about the .NET TransactionScope class lately, and I was wondering, what's the preferred approach here? Would I gain anything (readibility, speed, reliability) by switching to using using (TransactionScope _scope = new TransactionScope()) { using (SqlConnection _con = new SqlConnection(_connectionString)) { .... } _scope.Complete(); } What you would prefer, and why?

  • jQuery.getScript: data variable in callback undefined

    - by Hannes
    I'm trying to load an external JavaScript using jQuery's getScript(), like this: $.getScript("http://api.recaptcha.net/js/recaptcha_ajax.js", function(data) { window.alert(data); }); but as the alert window shows, the data variable in the callback function is undefined, unlike promised in http://docs.jquery.com/Ajax/jQuery.getScript#urlcallback. Anyone know why this might be? Thanks.

  • Dots and spaces in variable names from external sources are converted to underscores

    - by Brandon
    Trying a bit of AJAX, and I find that much of my data is littered with underscores! Documentation confirms that this is working as intended. Any way to pass my form information to PHP intact? I'm using CodeIgniter, so my pass looks like /controller/function/variable, receiving controller: controller{ function($v=0){#what once was hello world is now hello_world...} } I can't very well do an undo, data might contain an underscore. Thanks, Brandon

  • javascript: why to "sign-prefix" a variable?

    - by harald
    hello, i'm currently looking at a little 3rd-party javascript library and i see a lot of "sign-prefixed" variables in it: function_call(+value); i know, that you can swap the sign, if you prefix a variable with '-', but why to prefix something with a '+' -- it doesn't do anything to the value, no? thanks in advance!

  • Member variable pointers to COM objects

    - by drelihan
    Hi Folks, Is there any problem with keeping member variable pointer refernces to COM objects and reussing the reference through out the class in C++. Is anybody aware of a reason why you would want to call .CreateInstance every time you wanted a to use the COM object i.e. you were getting a fresh instance each time. I cannot see any reason who you would want to do this, Thanks, (No is an acceptable answer!!!)
